Christie Brinkley's lawyer is talking to ET about her ex-husband Peter Cook's appearance on Friday night's episode of ABC newsmagazine "20/20."

In the "20/20" interview, Cook seems to seek to redeem himself in the public eye after a very public divorce with Brinkley that revealed that he had used pornography and had an affair with a teenage woman. He tells Barbara Walters in the interview, "My hope is that the world will see that I'm not the scum bag pervert that I've been painted to be. The misinformation that came out during the trial is the elephant in the room. It's the elephant in the room for my kids. And I'm hoping maybe if I can correct some of the wrongs."

On behalf of Brinkley, lawyer Robert Stephan Cohen, released the following statement: "Christie Brinkley initially sought to settle this matter privately. The state of NY is an open court system. It was Mr. Cook who sought to lock the courtroom to the media. Judge Cohen applied the law and Peter's request to bar the media was denied. This was not Ms. Brinkley's doing, it was the law."

"Mr. Cook has chosen to breach the confidentiality agreement in the divorce settlement, a provision agreed upon in court to protect the children and allow them to put this ordeal behind them.

"This is a tragedy. Mr. Cook has proven once again that the court appointed psychiatrist Dr. Stephen Herman was right when he testified that Peter Cook has an insatiable ego and needs constant reassurance. Mr. Cook continues to put himself first, ultimately hurting the children.

"The court awarded Ms. Brinkley full custody of the children and all decision making concerning them. That decision speaks for itself.

"Ms. Brinkley plans to explore her legal options."

Earlier this week, ET confirmed that Brinkley had requested a restraining order against her ex-husband, and it was denied. Her attorney said at that point, however, "The Court Order mandates that since Peter Cook has the children this weekend, his parenting has to be away from his home and he can't expose them to the '20/20' broadcast. Christie Brinkley's sole concern is to protect her children."

On the other hand, Cook's attorney, James Winkler, told ET, "The restraining order they sought was to suspend visitation this weekend because of the "20/20" broadcast, which Mr. Cook never had any intention of showing to the children. The restraining order was denied."
